Carlo Ancelotti has decreed this to be a game the champions simply have to win to propel them out of a mid-season blip, though they will hardly relish the visit of Everton. David Moyes's side have drawn at Stamford Bridge on their last four visits – they have not lost at Chelsea since the spring of 2006 – and, even without the suspended Mikel Arteta, they will be awkward opponents. At least Chelsea's walking wounded are on the mend, with John Terry to start, Michael Essien also restored and Frank Lampard edging towards a return. This team needs to generate some momentum.
